Floor jack, yes. This isn't a car you will want to take to the local service station. You need to do some things yourself, and a floor jack is among the most handy things.
Probably the rear A frame bush, tyre rotations and oil changes will be the more common uses. And checking out the damage after going over a curb, lol. I actually did it. Being that low to the ground, it's not always obvious how deep a step or drop is until you go over it.
Welcome to sevening!
Those Allstar dollies do rotate to be perpendicular and flat.
But, yes, it's not likely you will need them very often. They're expensive for a single time use item.
The other dolly solution I like are these wheel dollies. I'm partial to one kind over the other. BOTH can slip out from under the wheel, but the diamond plate V type is far less stable.
Once on the ground on its wheels, on these dollies, the 7 moves around easily.
